Question

I need to use Maven to add a new buildCommand in my .project file.

My .project file (it was created by Maven):

<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
<name>myProject</name>
<comment></comment>
<projects>
</projects>
<buildSpec>
    <buildCommand>
        <name>org.eclipse.jdt.core.javabuilder</name>
        <arguments>
        </arguments>
    </buildCommand>
    <buildCommand>
        <name>org.maven.ide.eclipse.maven2Builder</name>
        <arguments>
        </arguments>
    </buildCommand>
</buildSpec>
<natures>
    <nature>org.eclipse.jdt.core.javanature</nature>
    <nature>org.maven.ide.eclipse.maven2Nature</nature>
</natures>

I have to add the following buildCommand:

<buildCommand>
        <name>org.eclipse.ui.externaltools.ExternalToolBuilder</name>
        <triggers>auto,full,incremental,</triggers>
        <arguments>
            <dictionary>
                <key>LaunchConfigHandle</key>
                <value>&lt;project&gt;/.externalToolBuilders/myLuncher.launch</value>
            </dictionary>
        </arguments>
    </buildCommand>

Someone has any idea how I can do this?

Thanks for your answer Attila – with some minor modifications I made it work. I tried to edit your post, but the edit was not accepted…

I used the plugin in the following way:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-eclipse-plugin</artifactId>
    <version>2.7</version>
    <configuration>
        <additionalBuildcommands>
            <buildCommand>
                <name>org.eclipse.ui.externaltools.ExternalToolBuilder</name>
                <triggers>auto,full,incremental,</triggers>
                <arguments>
                    <LaunchConfigHandle>
                    &lt;project&gt;/.externalToolBuilders/myLuncher.launch
                    </LaunchConfigHandle>
                </arguments>
            </buildCommand>
        </additionalBuildcommands>  
    </configuration>
</plugin>

I use the version 2.7 and not 2.9 because it allowed me to use the command eclipse:m2eclipse and then to use the Project with m2eclipse Plugin
